Title: Surgical instrument for treating female urinary incontinence
Inventor: CLAREN JAN
IPC: A61B17/42
Filed: 1995-08-28
Abstract: The invention relates to a surgical instrument and a method for treating female urinary incontinence. The instrument comprises a shank (10) having a handle (11) at one end thereof, and two curved needle-like elements (21A, 21B) which are connected at one end thereof each with one end of a tape (26) intended to be implanted into the body. These elements can be connected one at a time with the shank at the other end thereof to form a curved end portion of the shank and are intended to be passed into the body via the vagina, each element being dimensioned to extend from the inside of the vaginal wall over the back of the pubic bone to the outside of the abdominal wall. When practising the method the tape (26) is passed into the body via the vagina (28) first at one end and then at the other end at one side and the other, respectively, of the urethra (30) to form a loop around the vaginal wall. The tape is extended over the pubis (31) and through the abdominal wall (32) and is tightened. Then, the tape ends are cut at the abdominal wall, and the tape is left in the body.

Title: Method for the Removal of Carbon Dioxide Present in Gases and Absorbent
Inventor: SUZUKI HITOMI
IPC: B01D53/34
Filed: 1997-03-17
Abstract: This invention provides a method for the removal of carbon dioxide present in gases which comprises bringing a CO2-containing gas into contact with an aqueous solution containing at least one amine compound of the general formula [l]                           (see fig.I) wherein R1 to R8 may be the same or different and each represent a hydrogen atom or an alkyl group of 1 to 4 carbon atoms, and m is 0 or 1.  The method of the present invention makes it possible to remove carbon dioxide efficiently.  In particular, since carbon dioxide can be easily desorbed by heating the aqueous solution having absorbed carbon dioxide, the thermal energy required for regeneration of the aqueous solution can be reduced.

Title: Gas-controlled arc apparatus and process
Inventor: ROGOZIN ALEXANDER F
IPC: H01J37/32
Filed: 1997-04-04
Abstract: An improved gas controlled arc vapor deposition process and apparatus are disclosed.  Process gas is selectively introduced through the cathode evaporation surface of a cathode to create and maintain a process gas activation zone immediately adjacent to the cathode evaporation surface.  Cathode structures having process gas passageways formed therethrough and porous cathode structures configured from gas permeable materials are disclosed.  The concentrated introduced gas in the process gas activation zone significantly increases the degree of excitation, dissociation and ionization level of process gas atoms and molecules, which sharply lowers the threshold of synthesis reaction on the cathode evaporation surface and changes the nature and operation of the cathode spots. Deposition coating processes are performed at low chamber gas pressures, enabling more of the highly charged plasma particles from the process gas activation zone to reach the substrate  for providing dense, smooth, hard, macroparticle-free coatings with more efficiency and at higher deposition rates.

Abstract: An apparatus and method associated with a muticolor printer for rendering gray images with black toner only that might otherwise be rendered with black toner and/or other colors of toner (such as cyan, magenta and yellow). The printing includes a processor for performing an undercolor removal operations for rendering such gray images; a color level sum "s" is determined by summing an absolute value of a red level "r" minus a green level "g"plus the absolute value of the green level "g" minus a blue level "b" plus the absolute value of the blue level "b" minus the red level "r". This sum "s" is compared to a predetermined or setable color separation removal threshold "t". When the color level sum "s" is less than the color separation removal threshold "t", the gray image is rendered with black toner only.

Title: Spectral subtraction noise suppression method
Inventor: H NDEL PETER
IPC: G10L21/0264
Filed: 1996-01-12
Abstract: A spectral subtraction noise suppression method in a frame based digital communication system is described. Each frame includes a predetermined number N of audio samples, thereby giving each frame N degrees of freedom. The method is performed by a spectral subtraction (150) function ~(.omega.) which is based on an estimate (140) ~v(.omega.) of the power spectral density of background noise of non-speech frames and an estimate (130) ~x(.omega.) of the power spectral density of speech frames. Each speech frame is approximated (120) by a parametric model that reduces the number of degrees of freedom to less than N. The estimate ~x(.omega.) of the power spectral density of each speech frame is estimated (130) from the approximative parametric model.
